Yes, trading off latency to save bandwidth is definitely an incorrect  
approach. Bandwidth will keep increasing much faster than latency  
decreases (and there are hard physical limits to decreasing latency, while  
bandwidth could go up to infinity).

On high-latency high-bandwidth connections (satellite, 3G/4G) it may  
already be cheaper to download all versions of all images than to wait for  
CSS to be able to select the right ones to load. Solution that requires  
page layout for image loading is a step backwards for performance.
